Maximum likelihood estimates of selection intensity and mutation rate in the kai gene family of N. linckia based on the Poisson random field model

Sites	No. of sites	u	μg	Ne*	γ	LLexp	LLobs	P, one d.f.
Synonymous	178 sites	5.84  ± 1.44	3.28 × 10−2  ± 0.81 × 10−2	7.81 × 106  ± 1.93 × 106	2.84  ± 3.84	−38.799	−35.342	0.0085
Nonsynonymous	254 codons	9.43  ± 3.56	n.a.	n.a.	−3.76  ± 2.46	−19.984	−13.672	0.0004

u, total mutation rate (scaled to N_e); μ_g, mutation rate per site per generation (scaled to N_e); γ, selection coefficient (scaled to N_e); LL_exp, expected log likelihood (provided γ = 0); LL_obs, observed log likelihood (for the obtained γ); n.a., not applied; d.f., degree of freedom. 

^*Estimated with μ_g = 4.20 × 10⁻⁹ (assuming per site per year μ = 4.20 × 10⁻⁸ and 10 generations per year on average).
